Magnetometer price

Type & Sensitivity: Simple hobby modules cost a few hundred PKR or tens of USD; industrial/academic‑grade sensors run much higher.

Axes & features: 1‑axis vs 3‑axis, addition of an interface (I2C/SPI), data logger capabilities, calibration features, etc.

Application/accuracy: A magnetometer for drones or geophysics will cost more (better resolution, lower noise) than a simple compass module.

Brand and supply chain: Imported modules may have customs/duty added in your region, affecting final price in PKR.

Quantity & bulk pricing: Some datasheets show bulk discounts (e.g., 1000‑piece lots at much lower unit cost).
